Manchester City manager Pep Guardiola speaking to Sky Sports: "We played incredible from the first minute until the end. We created an incredible amount of chances. We were pressured but we did it. We kept our cool and we were patient. We know we will always get chances, it was important that we stayed calm ahead.
"I told them at half-time to keep going for it, to keep attacking. It is the only way. There was no space, it was almost impossible but we did it and that is why I am delighted."
Southampton manager Ralph Hasenhuttl: "To come here twice after losing 9-0 is not the easiest moment for a team but I think it was a chance to show up today, and we did, and it was really a pity that we didn't get something for the amazing work we did today.
"We had to show a reaction, we know that Tuesday was the first step and we knew we had to do it better than on Tuesday because the City team today was their first team, their A team, with all their best-performing players.
"And our squad today was unbelievably committed, and unbelievable defending, following the game-plan and investing so much in defending our net.
"It was very difficult today for City to create chances - I don't think they had a lot, only at the end was it open because we wanted the equaliser but until then I think they haven't seen a lot of chances.
"They had a lot of possession, yes sure, that is normal against this team but I think this was the only way how we could play against such an opponent. We did it in a fantastic way."
